Android Studio無法識別我的設備 - LG Spirit 4G

Question

我有開發人員選項啓用，驅動程序更新（稱爲操作系統win10），我按照文檔的說明。我的清單：

<application 
    android:debuggable="true" //this line says it shouldnt be harcoded? 
    android:allowBackup="true" 
    android:icon="@drawable/ic_piano" 
    android:label="@string/app_name" 
    android:supportsRtl="true" 
    android:theme="@style/AppTheme"> 

而構建graddle文件：

 android { 
    // Top-level build file where you can add configuration options common to all sub-projects/modules. 

    buildscript { 
    repositories { 
    jcenter() 
    } 
    dependencies { 
    classpath 'com.android.tools.build:gradle:2.2.2' 

    // NOTE: Do not place your application dependencies here; they belong 
    // in the individual module build.gradle files 
    } 
    } 

    allprojects { 
    repositories { 
    jcenter() 
    } 
} 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 
android { 
    buildTypes { 
     debug { 
     debuggable true 
     } 

兩個清單，並構建代碼的文檔複製。但它無法build.graddle。它說︰expectin'}'發現「 我不知道這是什麼意思，因爲我已經做了所有的文件說。我已經在這裏所有的答案，所以沒有任何工作......任何ideias 鏈接：https://developer.android.com/studio/run/device.html

你搞砸了你的build.gradle，它應該是這樣的：

// Top-level build file where you can add configuration options common to all sub-projects/modules. 
    buildscript { 
     repositories { 
       jcenter() 
     } 

     dependencies { 
      classpath 'com.android.tools.build:gradle:2.2.2' 

      // NOTE: Do not place your application dependencies here; they belong 
      // in the individual module build.gradle files 
     } 
    } 

    allprojects { 
     repositories { 
      jcenter() 
     } 
    } 

task clean(type: Delete) { 
    delete rootProject.buildDir 
} 

請注意，這是你的頂級的build.gradle，它會坐下在你的項目的根目錄中，應該有另一個 build.gradle在一個可能被稱爲的文件夾內這是你添加和修改android{} gradle clojure的文件
